Be it known' that l, Anfroiv von lnnrnnr, a subject of the Kino oi' Hungary, residingg,lr at Vienna, Austria-Elwin Ilary, have inyented certain new and vuseiu improvements in Gras-Producers; and l do hereby declare the following to be a full, clear, and exact deff Asoription oi the invention, suchv as will en able others skilled in the art to which it vappertains to make and use the same, ence being, had to the accompanying draw-- ings, and to letters or figures of referenee marked thereon, which form a part of this specitic-ation.

rl'his invention relates to rotary grate gas producers of that lrind in which a rotating dii 'pan arranged at the bottom of a stationary shaft carries the grate which rotates with refern the pan and is formed with hlovv holes fori the ain The rotary pan is usually vided. with a `Water seal 'for sealin shaft., that is to say, for preventing generated and the air ing at the bottoni of ashes may Without di'oulty hev discharged through the Water. Theseflinovvn arrangements give an excellent ei'ect When pressures are used which do not greatl exceed the atmospheric pressure, but higher pressures are to be used in producers, the Water seal arrangements hitherto usedprove insuilicient,' especially'with respect to the ash diseharga rlhis 'will he readily conceived troni the fact that the pan must have prol' a'j considerable height as the Water on the outside will rise to a point corresponding to the pressure Within the shaft. Of course a pan of that kind renders a continuous discharge ot the ashes very ldiilicult or even impossible, the discharge oi thel ashes out oit the pan requiring a reduction of the pressure and 'thereby decreasing the output of the producer and interfering with its regular and. erhcient Working.

Such arrangements however, present 'the Well known serious disadvantages which led to the construction-of rotary ash pans for dis-- fuel Moreover charging thev ashes, the chamber beneath the shaft being filled very rapidly, and thus no Vcomplete"combustion -ok the fuel taking place, when no special means are provided Lfor preventing this 'rapid descent or the g the means usually provided for the (purpose, namely the provision of a deep be of noncomb\'stible inaterial under 'the` lfuel or the likaha've not proved very eileetiveu No'vv thisinvention has lor its object to removetlie' diiliculties arising in connection with the high pressure blst, Without alter ing the mo e of discharging the ashes used iinvvater seal arrangements, in which the ashes have to "pass underneath the shaft through the'rotating' pan inwhichthey accumulate on the'outsiderbei'ng discharged continuously from it v`over its'outer upper edge by means of an abutment surface or plate and a conveying-scoop.

" 'According to this invention the water is dispensed with, the 'rotaryv pan being hoiised in 'an annular air-tight' chamber surround ing the lovver end of the shaft and in closed lcorniect'ion therewith which prevents the Communication vvith the outer atmosphere, this chamber being villed'Vvvith air or' gas of exactlythe'same pressure as thatjof the air blown in by the' grate; The discharge o' the ashes out of the shaft is then'ab'y'lelt` unaltered, beingcontinuously effected from the producerintn a discharge `chamber'vprovided adjaoent the shaft at the point of discharge-Which for'the purpose of discharg ing the ashes fromitself is adapted to be placed temporarily in eommuniation with an ash pit through an ash. passage provided the pointmottdisoharge, and adapted to be closed in an air-tight manner. il; further advantage in enabling a Water seal to be dispensed ivith is that the gases generated in the producer are not liable to be A .impaired by .becoming charged with Water vapor.
